How does pollution affect farming?
That depends on the type of pollution and the crop or form of
livestock you are referring to. In terms of simple water pollution, if a
source of pollution upstream or uphill from a farming area releases chemicals
into the environment, they usually either
1) evaporates, in the case of volatile chemicals,
2) dissolve into the groundwater, where they will then be picked up by plants
and often either incorporated into the plant's tissues or kills the plant
3) sits there, in the case of non-water-soluble solid pollutants.
In the case of air pollution, mostly your concern is acid rain. Nitrogen and
sulfur oxides react with rainwater to form nitric and sulfuric acids, which in
high enough concentrations cause chemical burns and cellular damage. Animals
are also affected by the pollutants, developing problems ranging from
infertility to various digestive ailments and death.
